Well penned and well said. I think the biggest part of the problem is that people ignore that they do not act in a vacuum, that action they take impacts everyone around them, the society in which they act, and even the ecology in which they act. They never stop to consider first if what they do will be kind or cruel. While all of us obviously fail this way, too many people seem to live out all their existence this way.
It does seem to be that way for some... They either never learn, or neve care.
